Quantum criticality and first-order transitions in the extended periodic Anderson model
I. Hagymasi, K. Itai, J. Solyom
We investigate the behavior of the periodic Anderson model in the presence of - Coulomb interaction () using mean-field theory, variational calculation, and exact dia…

Hubbard physics in the symmetric half-filled periodic Anderson-Hubbard model
I. Hagymasi, K. Itai, J. Solyom
Two very different methods -- exact diagonalization on finite chains and a variational method -- are used to study the possibility of a metal-insulator transition in the symmetric…

Emergence of Quintet Superfluidity in the Chain of Partially Polarized Spin-3/2 Ultracold Atom
G. Barcza, E. Szirmai, Ö. Legeza +1
The system of ultracold atoms with hyperfine spin might be unstable against the formation of quintet pairs if the interaction is attractive in the quintet channel. We have…
